[plt-scheme] schemeunit and require-library

["Jose A. Ortega Ruiz" <jaortega@acm.org>]

hi,

i've downloaded the schemeunit plt, version 1.1, and installed it on
drscheme/mzscheme v200 alpha 12 for linux. according to the
schemeunit's docs, i should use the form 'require-library' to load the
library's definitions, but both drscheme and mzscheme say that
'require-library' is an undefined identifier... should i require any
other module/collection defining 'require-library'?  any other
suggestion? (i've asked help-desk about 'require-library' with no
look: there were no matches in the documentation!).

thanks for your help!

cheers,

jao
